Text Solution

Verified by Experts

Abnormal semen is responsible for male infertility in more than `75%` cases. The following semen problems are possible.
• Low sperm count (oligospermia) Serm count should be 20 million sperms/`"mL"^(3)` of semen. If the count is under 10 million, there is a low sperm concentration.
• No sperm If a man ejaculates and there is no sperm in the semen.
• Low sperm motility The sperm cannot swim as effectively as it should.
• Abnormal sperm Sometimes the sperms have unusual structures, making these more difficult to swim towards the egg and fertilise it.
